A decade after published reports that scientists had cracked the code of our genetic blueprint, one of America's most prominent scientists has applauded an important milestone: the first patients to benefit directly from that effort, including a Wisconsin boy, Nicholas Volker. Volker, a 6-year-old whose story was chronicled in a Journal Sentinel series, is among three patients highlighted in an essay by Francis Collins, director of the National Institutes of Health. Collins' essay, "Faces in the Genome," appears in today's issue of the journal Science. Collins' stature as the head of NIH and a leader in the Human Genome Project reinforces the significance of what doctors in Wisconsin accomplished by sequencing Volker's DNA and using the results to diagnose and treat him. Collins' comments also underscore the growing push to bring DNA sequencing into the clinic.
